To all whom t may concern:

Be itknown that I, ANDREW P. ANDERSON,

a citizen of the United States of America, ref.

siding at Stoughton, in the county of Dane and State of Wisconsin, haveinvented certain new and useful Improvements in Harrows, of which thefollowing is a specification, reference beinghad therein to the'accompany'- ing drawings.

This invention relates to certain new and useful improvements inharrows, and relates more particularly to that class generally known aswheel-harrows or sulky-harrows.

The invention has for one object to con struct a harrow of this typewith a series of vibratory or longitudinally-oscillating dragbarsarranged in two sets, with one of Said sets actuated through gearingconnected to the one drive-wheel and the other of said sets actuatedthrough like gearing connected with the opposite drivewheel.

Another object of the invention is to construct a barrow of this type inwhich each drag-bar will be independent of the other dragbars forelevation to pass an obstruction or the like, together with meanswhereby all the drag-bars of each set may be simultaneously elevated tothe inoperative position or lowered to their working position, whichopera tion may be controlled by the driver from his seat by the movementof a single lever.

A still further object of the invention is to provide means foroperating both gears from a sin gle lever within easy reach of thedriversl seat and to provide-a frame of rigid construction which may, ifdesired, be constructedy from ordinary angle-iron.

The invention further consists in the novel construction, combination,and arrangement ot' parts, as will be hereinafter more specificallydescribed and then particularly pointed out in the claims.

Briey described,the elements entering into the combination in myimproved har-row are a frame of especia-l construction, the axles forthe drive-wheels, journaled in said frame, the drive-wheels mounted on.said axles, the two trains of gearing, and the series of drag-bars,these latter vdivided into two sets, one set for each train ot' gearing.These drag-bars have a vibrating or oscillatory movement when in theworking position during the travel of the barrow and are pivotallysupported at their forward ends in such a manner that when one of thebars engages a stone or like obstruction the other bars will not beaffected thereby; but the bar alone that engages the obstruc- 1'tionwill elevate, so as to clear such obstruction. VAt their rear ends thesedrag-bars are swiveled from a cross-rod in such a manner as to permittheir vibratory movement and also the independent elevating or loweringof v one bar with respect to t-he remainder. An elevating and loweringframe for the drag-bars is carried by the truck-carriage frame and isoperated by a lever located adjacent to the drivers seat, while by meansot' a separate lever, also located adjacent to the driveris seat, theclutches controlling the two trains of gearing are thrown into or out ofoperative relation. All of this construction, together with the minordetails, will now be described specifically, v ence will be had to theaccompanying drawings, forming a part of this specification, and

employed for designating like parts through out the several views of thedrawings, in

Which- Figure lis a top plan View of my improved harrow, showing therelative position of the two cranks which operate the vibratory or andin such description, refer# wherein like numerals of reference willbeoscillating draglbars. Fig. 2 is a longitudinal f sectional view oftheharrofw, taken on the line 2 2 of Fig. l. Fig. 3 is a rear view showingthe drag-bars in the operative or working position. Fig. 4 is a detailsectional view of a part of one of the drag-bars, the vertical arm towhich the drag-bars are pivotally connected at their rear ends, and ofthe horizon tal arm which connects the drag-bars with theoperating-cranks. Fig. 5 is adetail perspective view of a part of thetruck-carriage frame, the pivoted elevating and lowering frame for thedrag-bar, and also showing one of the drag-bars and its connection withthe operating-crank. Fig. 6 is a detail perspective view of one of thesleeves which form the swivel or toggle-joint connection fory the rearend of each drag-bar.

IV will tirst refer to the construction of the frame,which of the formherein shown is light, yet serviceable and durable. This frame consistsof the side rails 1, which in the form herein shown are constructed ofordinary angle iron or steel and are connected at their front ends byacross-brace 2, likewise of angle iron or steel with the ends bent inwardand bolted, riveted, or otherwise rigidly secured to the side rails 1.Arranged outside of these side rails 1 is a pair of auxiliary side rails3 of shorter length than the side rails 1 and composed of angle iron orsteel, with their ends 3 bent inwardly and rigidly secured to the siderails 1. A flat cross-brace 4 extends underneath the side rails 1, nearthe forward ends thereof, and has its ends rigidly secured to the outerfaces ofthe auxiliary side rails 3, near the forward ends thereof. Asimilar fiat cross-brace 5 extends underneath the side rails 1, near therear ends thereof, and has its ends rigidly secured to said siderails 1. Centrally supported on these two cross-braces 4 and 5 is a beam6, a convenient form for which I have found to be the ordinarychannel-bar, which beam, together with the side rails 1, forms supportsfor the bearings in which the operating-cranks of the drag-bars arejournaled. 'Mounted upon the side rails 1 and the auxiliary side rails 3are bearings 7 7, in which are journaled the axles 8 8, having thedrivewheels 9 mounted thereon. The hub of each of these drive-wheels isprovided with a rigid clutch-section 10, adapted to be engaged by themovable clutch 11, slidably mounted on the axles 8.

.Iournaled in bearings 12 12 on the side rails 1 and auxiliary siderails 3 and in a bearing 14, mounted upon the beam 6, are theoperating-cranks 15 and 16 for the drag-bars, the one crank being drivenfrom 011e drivewheel and the other crank from the opposite drive-wheel.These cranks are driven by gears 17, mounted upon the axles 8, whichmesh with gears or pinions 1S, mounted upon the cranks 15 and 16,respectively. The rods or shafts composing the cranks have their crankportions alternating in position, so that when one drag-bar is at theforward limit-of its movement the adjacent drag-bar on each side thereofwill be at the limit of its rearward movement. By providing two of theseoperating-cranks with a separate gearing for each crank two sets ofdrag-bars are formed, one driven by one crank and the other set by theother crank. The drag-bars 19 are provided with aseries of teeth 20,arranged'therein in two rows, or, in other words, in zigzagposition-that is, each alternate tooth being placed in the drag-baradjacent to the opposite side from that ot' the preceding tooth. Thesedrag-bars are preferably provided on their forward ends with a strap 2l,which is doubled and secured to the upper and lower faces of thedrag-bar, the loop thus formed beyond the forward end of and projectingor in a vertical position the bar acting as a buffer for the bar in'event of its engaginga stone or like obstruction in the soil. Thedrag-bars are supported at their forward ends by a chain or linkconnection 22 with a cross-bar 23, having its ends pivotally connectedto a yoke 24, which forms a part of the frame for elevating and loweringthe drag-bars and is pivotally supported at its ends from the side railsl of the main frame. At their rear ends these dragbarshave an eye 25secured therein, to which is pivotally attached an arm or rod 26,capable of both a vibrating movement, as required by the drag-bar in itsoperation, and of a vertical movement to permit the independent movementupwardly of each drag-bar when required. To support these drag-bars atthe rear end thereof and also to simultaneously elevate and lower thesame when desired, I pivotally attach to the side rails 1, near theirrear ends, a yoke 27, in the an gularl y-extend ing ends 28 of which ismounted a cross-shaft 29. Upon this shaft 29 is mounted a series ofdouble sleeves, consisting of two members 30 and 3l, the formerextending horizontally and receiving therein the shaft 29 and the latterextending transversely' to the former to receive the rods or arms 26,which are pivotally connected at their lower ends to the rear ends ofthe dragbars. These rods or arms 26 are bifurcated at their upper endsto receive stems 32, secured therein, preferably by both a metal rivetor screw and a wooden pin 3i. This construction is provided so that inthe event of a sudden blow being delivered against any one of thedragbars the plug or pin 34, being the weaker part,will naturally breakfirst, and the rigidity of thejoint between the rod 26 and stem 32 beingthus broken no further damage will be done to the parts. These stems intheir part projecting above the rods or arms 26 are likewise bifurcatedto receive the end of a n1etallic bar 35, which is pivotally attached bya rivet to said stem and has its under edge cut away, as at 3b', so asto permit the full sweep as requiredby the drag-bar in its movement.This bar is securely fastened in the rear ends of the crank-arms 37, oneof which is provided for each drag-bar and which connect at their otherends with the cranks l5 and 16, respectively. iVhen these cran k-armsare construct ed of wood, I may attach them to the cranks by cutting outa part of the forward ends, as shown at 38, placing the cranks in thisend of the arm, and then securing the part 38 in its position by bolts39. Likewise when these arms are constructed of wood in order to preventthe splitting of the same I preferably slit the rear ends of the same,insert the bars 35 therein, and secure the same by rivets 40, placingwithin the crank-arms at the termination ot' the slit for the receptionof the bar 35 a pin or rivet 41, against which the inner end of the saidbar may seat itself.

For the purpose of simultaneously elevat- IOO IIO

ing and lowering the 'drag-bars, I attach to the yokes 24 and 27centrally thereof, a yokelever 42 and pivotally connect to the side ofthe beam 6 a lever 43, which is connected by a link or strap 44 to theyoke-lever 42, so that when the said lever is moved backward itsimultaneously operates and moves downwardly the yokes 24 27, elevatingthe anglilar ends thereof, and consequently elevating at the same timethe cross-bar 23 and rod or shaft 29 and carrying the drag-bars upwardtherewith.

In order to engage both ltrains of gearing at the same time, and thuscause the simultaneous operation of both sets of drag-bars, I providetwo singularly-shaped levers 45 and 46, each having forked ends toengage the respective clutches 11 on the driveaxles. Thesetwoclutch-operatinglevers are each provided with oblong slots 47 toreceive headed pins 48 at the front ends of the side bars 1, the lever45 having its end pivotally attached to one end of a link 49 and thelever 46 having its end similarly attached near the opposite end of saidlink, the link being in turn pivotally supported upon a saddle 50,attached to the crosslbrace 2 and beam 6, so that when said link isactuated the ends of the levers 45 46, attached thereto, will besimultaneously moved toward or away from each other, according to thedirection in which the link is moved, and the clutches 11 consequentlybe simultaneously engaged with or disengaged from the clutch-sectionscarried by the hubs of the drive-wheels. The inner end of this pivotedlink 49 is bent upwardly and provided with a notch 51 to receive the endof the operating-lever 53, pivotally supported on the saddle 50, saidlever being held so as to retain the clutches in engagement or in theinoperative position by the rack-bar 54, mounted upon the saddle 50. Aseat 52 may be suitably supportedeither from the cross-brace 4 or fromthe beam 6, and a foot-rest 55 may be attached to the saddle 50 or atany point desired. The saddle 50 may, if desired, be extended, as shown,beyond the front crossbar for attaching the draft-equalizer thereto, andthe tongue 56 may be connected to the front cross-bar in any desirableor suitable manner.

I will now briefly describe the operation, assuming the parts to bcassembled as shown in Fig. 1 of the drawings, and the lever-53 being inthe position shown in this view, so as to cause the engagement of theclutches. Upon the forward movement of the harrow the gears or piuions17 18 cause the independent rotation of the crank-rods 15 16, operatingthe crank-arms 37 and imparting a vibratory movement to the rods or arms26 to cause the oscillation of the drag-bars 19. The cranks of thesecrank-rods being set alternately or at the half, it will be observedthat each alternate drag-bar of each set is at the forward limit of itsstroke when the remaining drag-bars of each set are at the limit oftheir rear stroke, and upon the engagement of any one of the bars withan obstruction the links forming the connection 22 between the forwardend of the bar and the bar 23 will by their collapsing or doubling uponeach other permit the elevating of this bar independently ot' all-theother bars,- so that the operation of the remaining drag-bars will notbe interfered with, and by reason of the rods or arms 26 slidingvertically within their sleeves 31 the elevation of the bars at theirrear ends will be permitted, as well as at the front end, so that suchobstructed bar may pass readily over its obstruction.

When moving the harrow from one field to another or at other times whenit is not desired for the vdrag-bars to operate, the lever 53 is thrownso as to disengage the clutches, the lever 43 thrown backward, and thedragbars elevated to a position underneath the main frame of the harrow.

While I have herein shown and also described the various elements indetail and also the manner of assembling the same, it will of course beevident that in the construction of the harrow various changes may bemade in the details thereof without departing from the general spirit ofmy invention.
